Therapeutic Levels of L-Glutamine

Glutamine Forté delivers a therapeutic level of L-glutamine in combination with Theracurmin™, a novel, water-dispersible form of turmeric with dramatically enhanced curcumin bioavailability.

L-Glutamine is a conditionally essential amino acid and an important fuel for enterocytes. The benefits of oral supplementation have been extensively studied. L-glutamine has been shown to:

  • Restore gut barrier function†
  • Promote healthy intestinal permeability†
  • Support a healthy immune system function†
  • Support healthy tissue repair mechanisms†

A Great-Tasting, Hypoallergenic Drink Mix

Because daily recommendations for L-glutamine can reach up to 30 grams daily in certain conditions, Glutamine Forté is formulated with a great-tasting, mild citrus flavor. Its convenient powdered drink mix format allows for flexible dosing and customized patient care. The product can be mixed in cold water or juice, or even in foods, such as yogurt or applesauce, for improved compliance.

Frequently Asked Questions

Why is glutamine not recommended for people with Crohn’s disease?

Glutamine has been tested in several studies with patients who have Crohn’s disease, and it not only didn’t help, but it appeared to exacerbate the condition. (1-4)

The reason why is not exactly known, but individuals with Crohn's disease have increased T cells, and glutamine's ability to activate T cells might be the problem. Glutamine is also metabolized to citrulline, which is in turn converted to arginine, a substrate for nitric oxide (NO) synthesis. Excessive NO could contribute to tissue injury and inflammation in individuals with Crohn's disease. (5)

Why does the caution statement for Glutamine Forte state that a healthcare practitioner should be consulted if you have active liver disease?

There is one study in which patients with liver cirrhosis and awaiting liver transplantation received oral glutamine (10-20 gram single dose) and experienced increased blood ammonia and impaired performance on certain neuropsychiatric tests.(1) This suggests a possible risk of exacerbating portal-systemic encephalopathy, which could be dangerous for cirrhosis patients. Although such a scenario is unlikely except in cases of severe liver disease, the dose used in the referenced study is achievable with Glutamine Forte, so we opted to err on the side of caution to allow the user and their doctor to make a fully informed decision.
